Market mapping

How to build a market map

A market map starts from a boundary, not a list. "Commercial HVAC service companies in the US Midwest with 5 to 50 million dollars in revenue" is a boundary. "Interesting industrial companies" is not.

1. Set the boundary from the mandate. Sector, geography, size band, and any ownership limits the fund has.
2. Assemble the universe. Pull every company that could fit from company registries, trade association member lists, licensing databases, conference exhibitor lists, and industry directories. Aim for completeness over quality at this step.
3. Enrich each record. Add revenue band, headcount, locations, ownership type (founder, family, PE-backed, corporate), and recent events. This is data enrichment, and it is where most of the effort goes.
4. Segment. Group companies by sub-sector, service line, or customer type, so gaps and clusters show up.
5. Rank against the mandate. Score each company on fit with the firm's strategy and on how reachable it is. Deciding whom to contact first is outbound scoring; sales teams run the same ranking as account scoring.
6. Assign and track. Give each top company an owner on the deal team, and log every contact so the map stays a working tool, not a slide.

Why market mapping matters in private equity

A market map turns sourcing from waiting into choosing. In the survey of 885 venture capitalists by Gompers, Gornall, Kaplan and Strebulaev, almost 30% of closed deals were proactively self-generated, while only 10% came inbound from company management. Self-generated deals start from knowing which companies exist. In private equity, Gompers, Kaplan and Mukharlyamov report that PE managers count making additional acquisitions among their sources of added value, and a buy-and-build plan is only as good as the list of possible add-ons.

Bain's annual Global Private Equity Report tracks deal, exit and fund-raising activity across the industry, which is useful context for choosing which markets to map. Its 2026 edition argues that today's deals demand faster earnings growth, which raises the value of knowing a market well before a deal comes up. Inside a chosen market, the map lets a firm approach founder-owned companies directly instead of meeting them for the first time in a banker's process. Venture funds build similar maps of a category to see which startups exist, who funded them, and where a thesis has no good company yet. Some also map the operators in a category, which gives a head start on underwriting talent when a company from the map comes up for a deal. In both cases the map is the starting point for deal sourcing, not a substitute for it.

Worked example: an add-on map for a platform company

Calder Street Capital, a fictional PE firm, owns a commercial HVAC services platform in Ohio and wants three add-on acquisitions in two years.

• Universe: 1,140 HVAC service businesses in six Midwest states.
• Size band (5 to 50 million dollars revenue): 310 remain.
• Ownership: 220 founder or family owned, 55 already PE-backed, 35 corporate subsidiaries. Calder Street keeps the 220 as primary targets and the 55 as secondary.
• Scoring: each of the 220 is rated on service overlap with the platform, customer mix, and distance from an existing branch. 40 land in the top tier.

The deal team splits the 40 among three people. Over the first year they reach 31, hold real conversations with 12, and sign a letter of intent with 1. Two other top-tier companies show trigger events (below) and move up the call list. The map took about six weeks to build. It is updated monthly.

How investors spot when a company becomes actionable

Most companies on a map are not for sale or raising today. The value comes from noticing the change. Common triggers, each a signal worth tracking:

• A first CFO or controller hire, which often precedes a sale or a raise.
• A new bank facility or the end of an existing one.
• The owner mentioning succession in a trade interview or at a conference.
• A close competitor being acquired, which resets local valuations.
• A founder stepping back from day-to-day roles, or a new president being named.

When a trigger fires, the history matters. A team that met the owner a year ago and kept the notes, which is the job of relationship intelligence, walks in with context. A team that did not starts cold.

Market map vs longlist vs deal pipeline

A longlist is usually cut from a market map. Once a company enters active talks it moves to the pipeline and through deal screening.

Common market mapping mistakes

• Starting from a database export. Commercial databases miss many small, founder-owned companies, which are often the best targets. Combine sources.
• Building it once. A map that is not updated is wrong within a quarter.
• Mapping without ranking. A list of 1,140 companies with no order tells the team nothing about who to call first.
• Ignoring ownership. A great company owned by a strategic buyer is rarely reachable. Ownership type belongs on every row.
• No owner per company. If everyone covers the top tier, nobody does.

How ScoringFactory approaches market mapping

ScoringFactory ranks a target market against a firm's mandate, learned from the deals the firm did and the ones it passed on, and watches for the moment a company becomes actionable. Each ranking cites the record behind it, and every meeting and note stays with the company. The deal team decides who to approach. See the private equity use case.
